It does not matter which Flight control law the A/C is in, (as long as the Autothrust is not u/s), it will kick in at the pre determined angle of attack and give Toga thrust, even with the thrust levers in the idle position
I am not sure about the above. This is my interpretation :
Alpha Floor protection (TOGA thrust and AOA "stall" protection) only works in NORMAL LAW !!
Alternate Law has a Low Speed Stability which may be overridden and the aircraft may stall
Direct Law has no such protections as all, and once again, you may stall !!
